Narrative:
After a complete run-up and thorough preflight; I departed ZZZ towards the coastline for a scenic flight. When throttling up; engine indicating instruments were in the green; with the engine running smoothly; manifold pressure was almost 30 in/hg and rpm was at full rpm; mixture was full rich; electric fuel pump was on; and I was on the right fuel tank. Aircraft accelerated smoothly and climbed well. I retracted my gear when out of usable runway and climbed at vy. Once climbing through 900MSL I brought the nose down for more of a cruise climb for visibility and accelerated to approximately 120mph and the aircraft continued climbing well. No power adjustments were made. Suddenly a large pop sound like a very very loud backfire occurred and the aircraft started vibrating. My engine indicating instruments were still in the green including oil pressure. I turned back to the runway as the engine was making partial power. The aircraft started smoking and for fear of an engine fire I accelerated the aircraft downward. This smoke turned out to be from the number 3 cylinder that had blown and was dumping oil directly onto the exhaust pipe. I had made the runway; landed; was able to safely taxi clear of the runway and shutdown on the taxiway. The aircraft had full oil and the dipstick was verified secured pre and post flight.

Title: Pilot reported a loud bang and smoke from engine on climb out; resulting in a precautionary landing.
Narrative: After a complete run-up and thorough preflight; I departed ZZZ towards the coastline for a scenic flight. When throttling up; engine indicating instruments were in the green; with the engine running smoothly; Manifold pressure was almost 30 in/hg and rpm was at full rpm; mixture was full rich; electric fuel pump was on; and I was on the right fuel tank. Aircraft accelerated smoothly and climbed well. I retracted my gear when out of usable runway and climbed at Vy. Once climbing through 900MSL I brought the nose down for more of a cruise climb for visibility and accelerated to approximately 120mph and the aircraft continued climbing well.
